REFRIGERATION APPARATUS PARTIC-U- LABLY ADAPTED FOR FREEZING FISH cari sunabch, weymoth, vMass..A Application July 16, 1935, serial No. 31,690 s claims. (o1. s2-102)v This invention Vrelates to `refrigeration apparatus, and the object ofthe invention is to provide an improved construction whereby cold/ air may be circulated in greater quantity .and with 5 greater efficiency than has been possible in constructionsheretofore -.known.

The invention is particularly applicable to -the construction of apparatus for storing and .freezing sh, whereby the same may be kept in mar- 10 -ketable condition.

The invention contemplates refrigeration apparatus comprising a compartment or building --including a'freezing or storage chamber, an air cooling chamber, and an air tunnel, the latter di- 15 vided into passageways for separation and .direction of air passing between the freezing or storage chamber and the air cooling chamber in currents which may be considered-'as originating in the air cooling chamber and returning thereto -after passage through the freezing o r' storage chamber, a refrigerating unit being located in the air'cooling chamber, and a blower or other air current producing devicebeing used to circulate.

the air through the refrigerating unit, air tunnel 25 and freezing or storage chamber, all as will be explained hereinafter morefully `and 'nally claimed.

AIn the accompanying drawing illustrating the invention, the gure is a perspective view of refrigeration apparatus embodying the principles ofthe invention, portions thereof being broken away to illustrate the construction and arrangement of the parts forming essential features of` the invention. The building or compartment'of the' apparatus comprises 'a foundation or bed I, preferablyin the form of a concrete slab the upper surfaceof which is provided-with heat-andlmoistu're' insulating coverings I', and upon this slab-are erected an outer. wall 2 and an inner Wall 3, these walls 2 and 3 being spaced apart by suitable framing l and the space between them being filled with heat insulating .material 5 of any suitable char- The interior of the compartment isA divided substantiallymidway of its .height by a horizontal partition or ceiling 'member 6, which extends from end to end Vof the compartment between the inner end walls 3, and this ceiling member prov and above it an air 'cooling .chamber 8f -Abbve the ceiling member vB and spaced a suitable distancetherefromis a false cei1ing, .parti tion or -platfor m' 9 upon whiclris supported arefrigerating 'unit 'III of any appropriate type,

vide's'below it a freezing'or'storage chamber 'I,

having an inlet II and an outlet I2 for the cir- 'culation of refrigerant therethrough.

`form 9, and to the exposed edges o f these studs 1 5 I are applied a plurality of spaced slats l5 forming lattice partitionsproviding between them and the adjacent walls, fiues or ducts for the passage of .air currents. lThe ceiling member is cut away above theends of the studs I 4 throughout 20 its portion which is included within the air tunnel to 'form at its side edges elongated Aslots through which air may'pass to and from thefreezing or storage chamber by way ofthe slatted or lattice partitions thereof andthrough the sepa-A 25 rate passages of the air tunnel, aswill be more fully vpointed out hereinafter. l'

The -air cooling chamber 8 's divided by a t'ransverse partition I'Iinto two sections, one of which contains the refrigerating unit I0; and may be termed the refrigerating. section, and the lother of which contains suitable air circulating means such as a blower I 8,'and may be. termed the return section'.-

chamber communicates withA the open end of one. of the'- passages of the air tunneLan'd the return section of the air cooling chamber'communlcates with the open end of the other 'passage of the air tunnel. Thus, air forced in the'direction of the arrows A and B will pass from' the return section of the air cooling chamber through the .blower and through 'the refrigeratng, unit and thence overthe end o f the platform 9 and into. 45 the open end. of. one of the passages of the air tunnel, whence itpasses downwardlygbetween the -studs I4 and into the freezing or storage chamber. Inasmuchasthev blower I8 while forcing- I air through the refrigerating unit andithenceinto 50 the freezing or storage chamber, as described-at the same time inducesv a current, of air irl-'the return section Jof the air cooling* chambe'ig-,the refrigerated air will pass from side to sideof the cooling chamber, as indicated by the arrows C, 55 Y and so upwardlybetween thestuds I l at the opposite side of the freezing or storage chamber, through the other passage of the air tunnel, as indicated by the arrows D, and thence from the return section of the air cooling chamber back to the blower, as indicated by the arrow E.

It will be noted that the shape of the passages oi the air tunnel, and of the ducts or flues of the lattice partition structure II-I5 at the sides of the freezing or storage chamber, is such as to produce the least obstruction to the flow of the air currents set up by the blower I8. Thus, the air circulates through the apparatus, and in contact with the goods placed in the freezing or storage chamber, in large quantities and with great facility, with the result that the refrigerating eii'ect produced is most eiiicient.

Beneath the refrigerating unit i0 is a drip pan i9 to catch the water produced during dei'rosting, and this pan has a drain 2D extending exteriorly of the apparatus.

As shown, the freezing or storage chamber y may be entered by way of one or more doors 2|,

and the air cooling chamber may be entered by way of one or more balconies 22 and doors 23.

The space between the ceiling member 6 and platform 9 occupied by the air tunnel serves to effectively insulate the air cooling chamber 8 from the freezing or storage chamber 1, and thus any heat which may be produced incident to operation of the blower i8 is prevented from adversely affecting the temperature of the freezing or storage chamber.

Various changes and modifications are contemplated within the spirit of the invention and the scope of the following claims.
